HENRY c. ROSE, or LEADVILLE, COLORADO.

sAsH-FASTENER.

SPECIFICATION forming' part of Letters Patent No. 417,589, dated December'17, 1889.

Application filed August 29, 1889. Serial No. 322.300. (No model.)

To all whom it may concern:

Be it known that I, HENRY C. ROSE, a citizen of the United States, residing at Leadville, in the county of Lake and State of Colorado, have invented a new and useful Sash- Lock, of which the following is a specification.

This invention has relation to sash-locks, and among the objects in View are to provide a combined lock and latch for sashes of simple and cheap construction, adapted to automatically latchv when the sash is lowered, and to be locked, if desired, against an upward raising, and to so arrange the parts that the sash may be unlatched in the act of raising the same. j

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of the lower portion of a sash and window frame provided with a combined latch and lock constructed in accordance with my invention. Fig. 2 is a rear elevation of the lock-plate and its mechanism in detail with the casing removed. Fig. 3 isadetail in transverse section on the line of Fig. 2. Fig. 4. is a detail in elevation of one of the latches or bolts. Fig. 5 is a detail view similar to Fig. 2, but showing the sliding bolt engaging the similarly-operating block.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 represents a window-sash, 2 the bottom rail, and 3 the window-frame. Countersunk in the inner surface of the rail 2 is the lockplate 4, the upper edge of which is provided with an upwardly-projecting'lift 5 secured thereto. The lock-plate is slotted vertically, as at 6, and in the same is mounted for vertical movementa threaded bolt or screw 7, to the rear end of which is secured a sliding block 8, the rear face of which is provided with recesses 9 and 10, the former being at the upper end of the sliding block and the latter at the lower` end thereof.

` 11 represents a` movable lift, which is secured to the front end and upon the outside of the screw or bolt 7. Bivoted, as at 12, to the rear face` of the lock-plate and at each side of the slot 6 is a bell-crank 13,

the upper ends of which overlap each other and rest upon the upper face of the sliding block 8.

The lower ends of the bell- L crank are provided with laterally-projecting of the latches or bolts there is mounted a coiled spring 18, the inner ends of which abut against the outer surfaces of the side walls of the lock-case. At suitable points upon the bolts 15 there are located laterally-proj ecting pins 19, which take between the coils of the springs 18, and thus 'said latches or bolts are normally maintained in such a position that their ends project from the edges of the sash, and thus when said sash is brought to a closed position the bolts register with the sockets 17 and are shot into the same by reason of the springs. In the manufacture of the lock I arrange the springs so that the pins 19 project through one of the intermediate coils, and should the springs become loose or lose their elasticity by reason of their constant use a few turns of the same, so as to lessen the number of coils outside of the pins, will serve to strengthen said springs, as will be readily apparent.

2O represents the locking-bolt, which ismounted in one of the side walls of the case, and which registers with a key-hole 21, through which a key is inserted to operate the bolt and project the inner end of the same into either the upper or lower of the recesses 9 or 10, formed in the sliding block 8.

The operation of myinvention is as follows: By inserting one thumb upon the lift 5 and the next finger under the lift l1 the latter lift is raised, which raises the sliding block 8 and the upper ends of the bell-cranks 13, and draws the lower ends inwardly,which retracts the bolts 15 from the sockets 17. The window may now be raised. lf desired to throw the latch mechanism out of operation, the key may be introduced through its slot 21 and the IOO bolt 20 shot into the recess 10,\vhich prevents the bell-cranks from swinging downward and the latches or bolts from extending beyond the edges of the sash. It will also be apparent that when the window is closed and the latch-bolts 15 are engaging the sockets 17, by introducing the key into the slot and operating the bolt 20, said bolt will be shot into the recess 9, and thus the window will be securely locked against raising until after the key is employed to bring the parts back t-o the position shown in Fig. 2.

As shown in Fig. 2, I may provide a spring 22, one end of which is secured to the rear of the lift 5, and the opposite end bears upon the inner ends of the bell-cranks 13, and thus also upon the sliding block S. Such a sprin g would serve the same function as the springs 18, and by its use the springs 18 Would be omitted.

It is apparent that I may employ locks with but a single latch and bell-crank, if desired; or in extremely-wide sashes I may employ two ot such locks, one at each side of the sash also, instead of the sockets I may employ the common ratchet-plates, as both the sockets and ratchet-plates are old in this art and are equivalent devices.

y Having described my invention, what I claim is 1. The co1nbination,\\'ith the lock-plate having a central vertical slot, a sliding block mounted in the slot, and a lift for actuating the same, of opposite bell-cranks overlapping the edge of the block and bearing thereupon, latch-bolts connected to the ends of the bell-cranks, springs for projecting the bolts, and a locking-bolt adapted to be projected into notches in the cam, substantially as specified.

2. The combination, with the bell-cranks mounted in the casing and the bolts connected with the bell-cranks, of springs for supporting the bolts and means for adjusting the spring, substantially as specified.

3. The combination, with the operating mechanism, of bolts loosely connected with said mechanism and provided with lateral pins, and coiled springs mounted fori-evolution upon the bolts and to be adjusted by the pins, substantially as specified.

4. The combination, with the sliding block 8 and means for operating the same, of the bell-cranks bearing on the cam and adapted to actuate bolts, and a sliding lockingb`olt adapted to be projected into either an upper or lower recess formed in the block, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of tivo witnesses. Y

HENRY C. ROSE.
